Development of a catalytic process for isomerization of D-glucose into D-fructose presents a crucial step for valorization of lignocellulosic feedstocks. This review focuses on basic catalysts as highly catalytically active and readily commercially available molecules and materials. The recent publications report that the solid bases catalyze the isomerization mainly heterogeneously with only a minor contribution of catalysis by OH⁻. For catalysis by amines, the hydroxide ions are on the contrary believed to be catalytically active species, though selectivity for d-fructose seems to depend on the amine structure. Buffers present another type of soluble basic catalysts which can be readily coupled with a facile separation of d-fructose from the reaction mixture via anionic extraction or adsorption upon complexation with phenylboronic acids.

将D-葡萄糖异构化为D-果糖的催化方法的发展为木质纤维素原料的增值提供了关键的一步。这篇评论集中在碱性催化剂上，这些催化剂是具有高催化活性和易于商购的分子和材料。最近出版报告，固体碱催化异构化主要是不均匀与OH催化的只有轻微的贡献^- 。对于胺的催化，相反地，氢氧根离子被认为是催化活性的物质，尽管对d-果糖的选择性似乎取决于胺的结构。缓冲液是另一种类型的可溶性碱性催化剂，可轻松与d轻松分离通过阴离子萃取或与苯基硼酸络合吸附而从反应混合物中得到果糖。
